Introduction
• Update from my 2017 talk
• Operating Systems• Hardware• Q/A as time permits
Supported Operating Systems
• Version 16.00 supports 32 bit and Vista• Only x64 editions of Windows supported post 16.00
– 32 bit EOL with production version 16.00– Vista EOL with production version 16.00
• Less than 1% of clients running 32bit or Vista
• Windows 7 and newer: Supported– Windows 7 EOL by Microsoft January 14, 2020– Windows 7 EOL by PLS ?

Recommended Operating Systems
• Windows 10 x64– PLS software “Just works”– Only OS that makes sense

Hardware Recommendations
• PLS-CADD vs. PLS-POLE / TOWER– PLS-CADD: RAM most important– PLS-POLE/TOWER: # cores most important
• Analysis time proportional to (Load cases) / (# cores)
• For all applications– SSD if files stored local (preferably a PCIe NVMe SSD)– Gigabit or 10 Gigabit to server if files stored remote
• If network slow use Compress XYZ and TIN files setting in PLS-CADD– A 40” 4k or multiple smaller monitors boost productivity– Do not need best/fastest GPU – spend the money on RAM and cores

Why no GPGPU?
• Performance numbers are peak for single precision. We use double precision typically a factor of 10 slower on GPU.– Double = ~16 significant digits– Single = ~7 significant digits
• Problems not parallelizable enough• Do not always guarantee IEEE 754 floating point semantics
– Our results matter!

• Tested on 32 cores: OK• Not all cores are equal
– Hyper-threading (HT)• Makes 1 core look like 2• Useless for FP bound apps• Half of cores Task Manager
reports for most processors are HT• 50% is full utilization
Hardware Limits/Details (Version ≤ 14.40)
6/24/2019 Power Line Systems 7
Hardware Limits/Details (Version > 14.40)• Tested on 32 cores: OK
– 32/64 cores with AMD Threadripper2990WX, but we have not yet tested
• Hyper-threading (HT)– Makes 1 core look like 2– Half of cores Task Manager reports for
most processors are HT– No longer useless!– Versions > 14.40 will use HT cores
for a 0-30% improvement in performance

Hardware Limits/Details Continued
• 96 GB of RAM used to load ~1 Billion XYZ points• Our code is unusually demanding and can reveal hardware
and driver faults– Overheating processor– Improperly cooled RAM– Ethernet card driver bug

What pushes the limits?
• LiDAR point counts – ever growing– Multiple lasers– Higher frequency data collection
• 1TB image– No compilations!– Prefer 10-100 images to 1000+ or just one big image
• Family and Framing Managers• 500+ Load cases
– Really?

Miscellany
• Intel best for PLS-CADD– Higher clockrate
• AMD ThreadRipper for TOWER and PLS-POLE– More cores
• Integrated GPS– GPS receiver must be natively supported by Windows
• Touch screens are supported6/24/2019 Power Line Systems 11
Budgeting Priorities
• Priority when budgeting– RAM (RAM speed matters)– Processor frequency (consider water cooled and overclocked)
– # cores Swap for TOWER/PLS-POLE vs. PLS-CADD
– SSD

Conclusion
• Windows 10 x64 is the way to go• PLS-CADD
– Buy RAM. Fast RAM and lots of it.• PLS-POLE + TOWER
– Buy cores. Many cores.• You should have a PCIe NVMe M.2 SSD
